Abstract

A microwave-assisted click chemistry synthesis of 1,4-disubstituted 1,2,3-triazoles is studied by in situ generation of aryl azides via the reaction of aryldiazonium silica sulfates and sodium azide, followed by coupling with a terminal alkyne in the presence of copper catalyst. These reactions are carried out in water under mild and heterogeneous conditions without using any additional ligands.
